IMPROVEMENT IN RAILROAD-CAR HEATERS.

. Q The Schedule referred to in these Letters Patent and making part ofthe name.

I Be it known that 1, WILLIAM MELLER, of McKeesport, in the county ofAllegheny, and State of Pennsylvania, have invented a newand usefulImprovement 1 in Stoves for Railway-Oars; and I do hereby declare tionand operation.

that the following is a full, clear, audexact description of the same,reference being bad to the acc0m-- panying drawings which form part ofmy specification, and to the letters and figuresmarked thereon.

The nature of my invention consistsin surrounding a stove with awater-chambenand connecting therewith pipes for distributing heatthrough the car; also, so arranging the water-chamber with relation tothe stove, that in case of an accident to the, cars, and the stoveshould be upset, the water will flow from the water-chamber into thestove, and thereby "'drown out or extinguish the fire in the stove. f

To; enable others skilled'in the art to make and use my invention, Iwill proceed to' describe its construc- In the accompanying myspecification? Figure l is a vertical section at line y of myimprovement'in stoves for railway-cars. V

Figure 2 is a-transverse section of the same when out through at line2:. i

Figure 3 is a side elevation of my improved stove for railway-cars.

In the accompanying drawings- A represents the casing which surroundsthe stove.

The space '5 between the casing A and stoveB drawings, which form partof 3 forms the water-chamber.

To the casing A are attached pipes g and h h. The pi pelt should beconnected with a water-reservoir, which should be elevated at least ashigh as the top of the stove. q l

.The pipe g should extend along the sides of the car near to the flooror alongon the floor of the ear,

of the armof the valve.

1 represents the grate of the stove. 0 represents the ash-pan, which isheld closed by means of the iron strap 9 and pins 10, as shown in ings,I will, therefore, without further description of:

the construct-ion, proceed to describe the operation, which is asfollows:

The water from the water-reservoir flows through I I pipe h into thewater-chamber i, and from it through the pipes g and h. Fire beingplaced in the stove B will heat the water in the chamber i, and thehottest water will flow out through pipe g and return back into thelower part of water-chamber 12 through pipe 71, and thereby heat the carby the hot water circulating through pipes, arranged as hereinbeforedescribed. In

case of an accident to the cars, and the stove should i be upset, theweight f will fall to.one side, and one or more of ,the valves 6 willfall back so as to allow the water in chamber 1} to flowthrough one ormore of the opening 2 in the stove B, and thereby drown out orextinguish the fire in the stove.

If the stove should be up-ended, valve -3 will close the opening 5 ofthe stove-pipe, as indicated by v the dotted lines marked-4. v

The advantages of my improvement in stovesfor railway-ears are, equaldistribution of heat through the car, and the extinguishing of thefirein the stove in case'of an accident,

Having thus described the nature, construction, and

operation of my improvement,

What I claim as of my invention is The combination and arrangement ofthe waterchamber 'i, pipes g, h, and h, valves 5 and 6, openings- 2, andstove B, the whole beingconst-ructed, arranged,

combined, and operating substantially as herein described, and for thepurposeset forth.

WILLIAM MELLER.
